i have a first time filer entered Canada 2023. When i tried to submit his return its giving me an error code of 110-B . I contacted efile helpdesk but no luck they cant give me any information to solve this problem. I was advice to contact the client for them to call CRA general inquiry to find out what exactly the name they have onfile but since first time filer CRA dont have a any records of anything. I tried everything putting middle name and checking first time filer. Client even gave me a copy of his SIN but no luck. Can anyone please guide me on how to solved this problem. Thank you
